A narrow-band green emitting KTb(PO) phosphor has been synthesized by a novel single-crystal growth approach involving the application of an inert flux. Its structural and spectroscopic peculiarities have been systematically studied by means of single-crystal X-ray diffraction, scanning electron microscopy, energy-dispersive X-ray spectroscopy analysis, and diffuse reflectance, infrared and photoluminescence spectroscopy. The layered framework of the title compound is organized by linking together slightly distorted phosphate tetrahedra with non-condensed TbO polyhedra into [Tb(PO)] sheets interconnected by potassium cations.

The title compound dipotassium gadolinium(III) phosphate(V) molybdate(VI), KGd(PO)(MoO), was synthesized from a high-temperature melt starting from GdF as a source of gadolinium. Its structure is isotypic with other ( O)(PO) compounds, where = Na, K or Cs, and = rare-earth cation, = Mo or W. The three-dimensional framework is built up from [Gd(PO)(MoO)] anionic sheets, which are organized by adhesion of [GdPO] layers and [MoO] tetra-hedra stacked above and below these layers.

The structure of this new compound features a 2D framework containing [EuPO] layers, which are composed of zigzag chains of [EuO] interlinked by slightly distorted PO tetrahedra. Isolated WO tetrahedra are attached above and below these layers, leaving space for the K counter-cations.

The asymmetric unit of the title compound, [Fe(CHBN)], contains two half independent complex mol-ecules. In each complex, the Fe atom is located on an inversion center and is surrounded by two scorpionate ligand butyl-tris-(1-pyrazol-1-yl)borate mol-ecules that coordinate to the iron(II) ion through the N atoms of the pyrazole groups. The two independent complex mol-ecules differ essentially in the conformation of the butyl substituents.
